INdibano ye-Flex ye-PCB iyahluka kwiNdibano ye-PCB engqongqo kwiNkqubo yokuVelisa

Indibano yePCB (iBhodi yeSekethe eShicileleyo) yinxalenye ebalulekileyo yokwenziwa kombane. Ibandakanya inkqubo yokunyuswa kunye nokuthengisa izinto zombane kwiPCB. Kukho iintlobo ezimbini eziphambili zeendibano zePCB, iindibano zePCB eziguquguqukayo kunye neendibano zePCB eziqinileyo. Ngelixa zombini zisebenza injongo enye yokudibanisa izinto ze-elektroniki, zenziwe ngokwahlukileyo.Kule bhlog, siza kuxubusha indlela indibano ye-PCB eguquguqukayo eyahluke ngayo kwindibano yePCB engqongqo kwinkqubo yokwenziwa kwemveliso.

1. Indibano yeFPC:

I-Flex PCB, eyaziwa ngokuba yi-PCB eguquguqukayo, yibhodi yesekethe enokugotywa, isongwe okanye ijijwe ukuze ilingane iimilo ezahlukeneyo kunye noqwalaselo.Inika iingenelo ezininzi ngaphezulu kweePCB eziqinileyo, ezinje ngokuncipha kokusetyenziswa kwendawo kunye nokuqina okongeziweyo. Inkqubo yokwenziwa kwendibano ye-flex PCB ibandakanya la manyathelo alandelayo:

a. Uyilo lwePCB oluguquguqukayo: Inyathelo lokuqala kwindibano yePCB ebhetyebhetye kukuyila ubeko lwesekethe oluguquguqukayo.Oku kubandakanya ukumisela ubungakanani, imilo kunye noqwalaselo lwe-flex PCB. Ingqwalasela ekhethekileyo inikwe ukulungiswa kweendlela zobhedu, ii-vias kunye neepads ukuqinisekisa ukuguquguquka kunye nokuthembeka.

b. Ukukhethwa kwezinto eziphathekayo: IiPCB eziguquguqukayo zenziwe ngezinto eziguquguqukayo ezifana ne-polyimide (PI) okanye i-polyester (PET).Ukukhethwa kwezinto kuxhomekeke kwiimfuno zesicelo, kubandakanywa ukumelana nokushisa, ukuguquguquka, kunye neempawu zomatshini.

c. Ukwenziwa kwesekethe: Ukwenziwa kwe-PCB eguquguqukayo kubandakanya iinkqubo ezinje ngefotografi, i-etching, kunye ne-electroplating.I-Photolithography isetyenziselwa ukudlulisa iipateni zesekethe kwii-substrates eziguquguqukayo. I-Etching isusa ubhedu obungeyomfuneko, ishiya i-circuitry efunekayo. I-Plating yenziwa ukuphucula i-conductivity kunye nokukhusela iisekethe.

d. Ukubekwa kwecandelo: Kwindibano ye-PCB eguquguqukayo, amacandelo abekwe kwi-substrate eguquguqukayo kusetyenziswa iteknoloji ye-surface Mount (SMT) okanye iteknoloji yomngxuma.I-SMT ibandakanya ukunyuswa kwezixhobo ze-elektroniki ngqo kumphezulu we-PCB ebhetyebhetye, ngelixa iteknoloji yomngxunya ibandakanya ukufakela imingxunya esele igrunjwe kwangaphambili.

e. I-Soldering: I-Soldering yinkqubo yokudibanisa amacandelo e-elektroniki kwi-PCB eguquguqukayo.Ngokuqhelekileyo kwenziwa kusetyenziswa i-reflow soldering okanye ubuchule bokusondeza amaza, ngokuxhomekeke kuhlobo lwecandelo kunye neemfuno zendibano.

2. Indibano yePCB eqinileyo:

Ii-PCB eziqinileyo, njengoko igama libonisa, ziibhodi zesekethe ezingaguqukiyo ezingenakugotywa okanye zijije.Zihlala zisetyenziswa kwizicelo apho uzinzo lwesakhiwo lubaluleke kakhulu. Inkqubo yokwenziwa kwendibano eqinileyo yePCB yahlukile kwindibano yePCB eguqukayo ngeendlela ezininzi:

a. Uyilo lwePCB engqongqo: Uyilo lwePCB engqongqo lujolise ekwandiseni ukuxinana kwecandelo kunye nokwandisa imfezeko yesiginali.Ubungakanani, inani leeleya, kunye noqwalaselo lwePCB zimiselwa ngokweemfuno zesicelo.

b. Ukukhetha izinto eziphathekayo: Ii-PCB eziqinileyo zenziwe ngokusebenzisa i-substrates eqinile njenge-fiberglass (FR4) okanye i-epoxy.Ezi zixhobo zinamandla amakhulu omatshini kunye nokuzinza kwe-thermal kwaye zifanelekile kwizicelo ezahlukeneyo.

c. Ukwenziwa kwesekethe: Ukwenziwa kwe-PCB engqongqo ngokubanzi kubandakanya amanyathelo afana nee-PCB eziguqukayo, kubandakanya ukufotowa kwefoto, i-etching, kunye ne-plating.Nangona kunjalo, izinto ezisetyenzisiweyo kunye nobuchule bokwenza izinto zinokwahluka ukulungiselela ukuqina kwebhodi.

d. Ukubekwa kwecandelo: Amacandelo abekwe kwi-PCB eqinileyo kusetyenziswa i-SMT okanye itekhnoloji yomngxuma, efana nendibano yePCB eguqukayo.IiPCB eziqinileyo, nangona kunjalo, zivumela ulungelelwaniso oluntsonkothileyo lwamacandelo ngenxa yolwakhiwo oluluqilima.

e. Soldering: Inkqubo yokuthengisela engqongqo PCB indibano iyafana naleyo yendibano PCB flex.Nangona kunjalo, ubuchule obuthile kunye nobushushu obusetyenzisiweyo bunokwahluka ngokuxhomekeke kwizinto kunye namacandelo athengiswayo.

Ukuququmbela:

Indibano ye-PCB eguquguqukayo kunye nendibano engqongqo yePCB ineenkqubo ezahlukeneyo zokuvelisa ngenxa yeempawu ezahlukeneyo zezinto kunye nokusetyenziswa kwazo.IiPCB eziguquguqukayo zibonelela ngokuguquguquka kunye nokuqina, ngelixa iiPCB eziqinileyo zibonelela ngozinzo lwesakhiwo. Ukwazi umahluko phakathi kwezi ntlobo zimbini zeendibano zePCB kubalulekile ekukhetheni ukhetho olufanelekileyo lwesicelo esithile sombane. Ngokuqwalasela izinto ezifana nefom factor, iimfuno zoomatshini kunye nokuguquguquka, abavelisi banokuqinisekisa ukusebenza kakuhle kunye nokuthembeka kweendibano zePCB.
